COMBINED HOT AIR AND WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 387,309I dated August'7, 1888.

Application filed August i, 1887. Serial No. 245.877.

To @ZZ whom, it may concern.-

Be it known that I, MICHAEL li'IAIIoNY, a citizen of the United States,residing at Troy, in the county of Rensselaer, State of New York, haveinvented certain new and useful Improvements in Combined Hot Air andVater Heaters, of which the following is a specification, referencebeing had t-herein to the accompanying drawings.

Myinvention relates to furnaces for heating houses in which are combinedthe advantages obtained from air-furnaces, whereby a renewal of airproperly heated is admitted into said houses with the economy ofhot-water heaters, in which the caloric can be conducted through smallpipes to any desired distance from the heater.

The object of my invention is to obtain a simpleandinexpensively-constructed apparatus, either portable or brickset, inwhich air and water can be heated and conducted to dit'Y ferent rooms ofhouses.

In the accompanying drawings, Figure l is a perspective of a heaterconstructed in accordance with my invention,the side andjacket beingbroken away to show the hollow walls of the tire-pot and thesuperheater. Fig. 2 is a perspective view of the upper portion of theheater constructed in accordance with my invention, showing one of thesmoke-deflecting plates and a cylindrical superhcater.

In said drawings, A represents the hollow baseplate resting on theiioor, through which air to be heated is broughtinto the apparatus, asin ordinaryhot-air furnaces. It has the ashpitBin the center thereof,upon which is placed the plate c, having in its center the grate D. Uponsaid plate is placed the firepot E, of castiron,made hollow, havinginner walls, e, to retain the combustible upon the'grate, outer walls,e?, on the sides,and top and bottom walls,

e", these walls forming a chamber, E2, in which water can be conductedthrough the pipe j, entering said walls close to the bottom thereof andbe carried oft" throughv a pipe at the top, being heated by the infiamedcombustible within said fire-pot.

To add to the heating capacity of the apparatus, there is above thefire-pot an annular hollow superheater, G, that is connected with (Nomodel.)

the upper edge of the hollow fire-pot by a series of vertical pipes, g,between which the flame and heated gases can pass on their way to theuptake H. To the top of the super heater are attached one or more pipes,g2, to conduct the hot water to radiators, coiis, or other equivalentdevices used in rooms to heat the air or other substances therein. lThetire-- pot and superheaterare inclosed in a drum, I, that rests upon thebottom plate, C. The top of said drum is closed, but its sides have twoopenings for the passage of smoke. rIhe upper opening is connected withthe due li, that enters the uptake H at a high point, and is used mainlyat the time a new tire is started. The lower opening is connected withthe flue h2, that enters the bottom of the uptake and gives an escape tothe smoke when the damper h in the flue 7L is closed. To cause theproducts of combustion to circulate evenlyaround the fire-pot the latterhas encircling its upper end a division-plate, E3, that extends abouttwo-thirds of its circumference, and from the ends of said plate arependent deliecting-plates E4, Fig. 2, that extend about two-thirds ofthe distance down against the outer walls of the re-pot.

The outer edge of the plates *3 Ei abut against the inner surface of thedrum I and form with the latter and the repot theinner smoke-lines ofthe device, and said device is inclosed, as usual, in a jacket, K, thatmay be single, as in Fig. l, or double, as in Fig. 2, within which theair to be heated is made to circulate, and is conducted in any suitabledirection from the openings Kt in the top thereof. The front of thejacket may be in one piece, as L, Fig. 2, provided with tire-door m, orsaid door be fastened to thejacket, as in Fig. 1, and through theopening closed by said door the fuel can loe introduced into thetirepot. The ash-pit is also provided with a door, N, having regulableopenings n, and between said doors there is a door, P, that closes anopening leading Within the drum I, through which the ashes falling intothe passage surrounding the iire=pot can be removed.

I am aware that tire-pots have been made hollow and provided with pipesfor the passage of water in and out therefrom, and that ICO horizontaland vertical division-plates have been placed in the smoke-'dues todeflect the products of combustion.

Having now fully described my invention, I claiml. In a combined hot airand water heater, the combination of a hollow tubular fire-pot pextending down to the level of the grate, aseries of pipes securedvertically to the upper end of said pot between its inner and outeredges and in communication with itsinterior, an annular superheatersecured to the upper end of said pipes,asurrounding division-platesecured to the top of the fire-pot and having pendent defleeting-platesat the ends tbereof,a drum inclosing` said lire-pot and superheater, anuptake leading from the top and also from the bottom ofsaid drum, and ajacket inclosing said drum, substantially as described.

2. The combination of the ash-pit and its zo top plate, a hollow tubularfire-pot, a series of pipes secured to the upper end of said pot,anannular superheater secured to the upper end of said pipes, a drumresting upon the top plate of the ash-pit, and a division-plate sur- 25In testimony whereof I affix my signature in 3o presence of twowitnesses.
